Canadians to dim the lights for 10th edition of Earth Hour Saturday

Canadians are being asked to join millions around the world in turning off their lights on Saturday night to mark Earth Hour.

The event was launched in Australia in 2007 as a way to draw attention to environmental issues including climate change, but this year’s 10th edition is as much a celebration as a call for action, according to the main organizer of the event.

Across the country – between 8:30 and 9:30 local time – people will be turning off their lights, shutting down appliances and taking a break from computers and TVs.
